Publication number: 20100300186Abstract: A pressure-measuring device is to be placed in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmission element projecting out of the housing, and a pressure sensor disposed in an interior chamber of the housing. On the one hand, the pressure sensor is braced on a fixation element. On the other hand, to detect a pressure prevailing inside the chamber, the pressure sensor is operatively connected to the force-transmission element. The pressure sensor has a straight-through recess through which an electrical line is routed. In addition, a positioning element is provided, which has a straight-through recess in a guide region, the electrical line being routed through the straight-through recess, and the positioning element having a reduced thickness in the guide region. This makes it possible to reduce friction of the electrical line in the guide region at the straight-through recess, so that the pressure measurement is improved.Type: ApplicationFiled: August 16, 2007Publication date: December 2, 2010Inventors: Christoph Kern, Ewgenij Landes, Michael Kleindl, Christian Doering, Steffen Schott, Pavlo Saltikov

Patent number: 7730771Abstract: A device for detecting the combustion-chamber pressure in an internal combustion engine is configured in such a way that the combustion-chamber pressure is able to be detected in a reliable and reproducible manner. To this end, a heating pin exposed to the combustion-chamber pressure is fixed in place in a housing of the glow plug with the aid of a fixation member. A sensor is affixed in the housing of the glow plug via a fixation element set apart from this fixation member. This sensor detects the elastic longitudinal expansion of the housing caused by the combustion-chamber pressure between the end of the fixation member facing the sensor and the fixation point of the fixation element on the housing. This device is preferably utilized in the automotive industry.Type: GrantFiled: January 13, 2005Date of Patent: June 8, 2010Assignee: Robert Bosch GmbHInventors: Thomas Ludwig, Christoph Kern
